Only thing I've seen recommended as far as prepping daily drivers for the track is getting the brakes bled.

So when I take my car in Monday for some coding work and I tell them about my Limp Mode experience, will the computer's history of the event point them in the right direction or will they blow me off? I'd love to go in telling them everything you've mentioned here, but if I'm "that guy" they'll give me attitude. As it is I had to explain the whole ASS coding to them.
